Application filed October 24, 1923. Serial No. 670,582.

To all whom it may concern.

Be it known that we, JACOB P. BnowN and JOSEPH A. STRANG, c tizens of the United States, residing at Paterson, in the 5 county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Shuttle Tensions, of which the following is a specification.

This invention. relates to loom shuttle 10 tensions, and particularly to that class of such devices in which a spring-actuated lev'er is provided with a series of guides which cooperate with another and fixed series of guides, alternating with the first series, in maintaining tension on the thread, which is adapted to extend in engagement with all the guides. The principal object is to provide a tension device, as said lever, which shall be simple and inexpensive in construction and have its guides readily removable therefrom and replaceable by others when they become worn, as by the cutting action of the thread.

We have shown the invention by way of 5 example in the accompanying drawing in .two forms, and it may be here stated that the invention in part broadly consists in a tension device including a body member having openings therein at intervals, guides resting on said member at one side thereof and projecting through said openings and at the other side of the member, and means, at and bearing against the other side of said member and extending through the several s guides, for securing them to said member.

In said drawing, Figs. 1 to 8 on the one hand and Figs. 9 to 12 on theother show the two different forms of the invention,

Fig. 1 showing the first form in side elevation in position in a shuttle;

Fig. 2 being a plan of the blank from which the body member of the device is formed;

Fig. 10 is a section on line 1010, Fig. 9;

Fig. 11 is an unde'rneath plan-of the {device shown in Fig.9; and I i F ig. 12 is a section on line 12 -121,'Fig. 10. i a

The l-oom shuttle a has its cavity Zitraversed by a fulcrum pinand the usual pinsaZ; forming the mentioned fixed series of guides. It also has, suitably. securedto a pin 6, the rubber orother elastic device 7 adapted to shift the lever equipped with the seriesof guides ries d contrary to the action of the thread A to be controlled. The improved tension device (hereine nbodied in the lever) is con: structed as follows: n t

Having reference, first, to the firsteight figures of the drawing: An elongated stiff sheet blank 9 is provided, the same having transversely elongated openings 7; arranged in a lengthwise series, equally spaced from each other. At each. side of the" blank, opposite each opening,

openlngs and projections occupy only a portion about one-half) of the length the remainder of which is left of the blank, plain. This plain end-portion of the blank is formed into a curl; j, adaptedto afford a fulcrum for the lever of the shuttle, downward, as at Z, and 7 with a hole m to receive the end o fl'the elastic device 7. Between thepairs of proj ections z' thematerialof the blank is pinched or folded,as; at n, Fig. 4, on acentral longitudinal axis so that thes'alien't side of the which coaet with the se-,.

is a projection i. The

on the fulcrum pin 0 and its extremity is bent -ay be provided fold is up; this leavesa downwardly open a channel- 0 (Fig.

7 The project/reuse are each bent on a transverse central axis (Figs.

4 and 7) so that pair of thus-bent projection-s, leaves a trans: verse channel or transversely elongated socket 29 (Fig. 4), further in a desirable curving upward of the ends of each transverse portion of the the salient side of the bend is in each instance down; this, asto each the bending resulting I Q blank which includes a pair of the proje'ctions 2', as shown by Figs, 7 and 8. The guides g, which are here in the form of circular (as ordinary glass) eyelets, are adapted to be seated in the sockets .1), as shown in Figs. 1, 4c, 6, 7 and 8 and in so doing they project through the material of the body member formed from the blank as stated, to wit, through the openings it, resting against the top side and protruding (into the chan nel 0) at the underneath side of said member. To secure the eyelets in place we provide the strip or tongue 1" of stiff elongated material which is introduced endwise into the channel 0 from its free end and is passed through the several eyelets, (in the present example, actually through their thread apertures g) beneath said member. By bending up its entering end, as at 0", this tongue may be made to bear against said member and thus by friction be retained in place; it may have a hook r at its other end bywhich it may be caught in removing it. Each guide is thus securely though removably held in place. The sides of the pair of sockets which receive each eyelet assist, as will be obvious, in keeping the eyelet in a definite upright position.

Referring, now, to Figs. 9 to 12, the body member is formed from an elongated blank 8 of sheet material having transversely elongated openings 8 in one end portion thereof and its other end portion formed with'a curl t and with its extremity u bent downward, the curl t and extremity a corresponding in form and function to the curl j'and extremity Z already described. In this case the openings .9 are formed by transversely slitting the material of the blank on pairs of parallel lines and pressing down such material between the lines in each pair, as indicated ata; in Fig. 10; the part of the material thus bent downward may be in each instance channeled lengthwise thereof as shoWn in said figure. The guides to, here also in the form of circular eyelets, are respectively set in the openings 8 and seated in the, channeled depressed portions 4). The guides having thus been arranged in their settings, a tongue 00, substantially the same as that already described, is entered at the under s de of the body member and through the several guides. The channeling of the depressed portions '0 in this instance assists in keeping the guides in a more or less definite upright position.

In another aspect of our invention the body member may be regarded as recessed at intervals, with the guides seated in the recesses (formed by the openings h or s) and stiff attenuated means (as r or 00) to hold the guides in place extending longitudinally of the series of guides and through the latter and also through said member at intervals.

lVe claim:

1. A tension device including a body member having openings therein at inter- Tals, guides resting on said member at one side thereof and projecting through the respective openings and at the other side of said member, and means, at and bearing against the other side of said member and extending through the guides, for securing them to said member.

2. A tension device including a body member having openings therein at intervals, guides having thread apertures and resting on said member at one side thereof and projecting through the respective open ings and at the other side of said member, and means, at and bearing against the other side of said member and extending through the apertures of the guides, for securing them to said member.

3. A tension device including a body member having openings therein at intervals, guides resting on said member at one side thereof and projecting through the respective openings and at the other side of sad member, and a substantially straight stiff holding device at and bearing against the other side of said member and extending through the guides.

&. A tension device including a body member having openings therein at intervals, guides resting on said member at one side thereof and projecting through the respective openings and at the other side of said member, and means, at and bearing against the other side of said member and extending through the guides, for securing them to said member, said member having transverse channels in which the guides are respectively seated.

5. A tension device including a body member formed from an elongated piece of stiff sheet material channeled lengthwise and having openings at intervals therein and each traversing its bend, guides received in the openings and resting on said member at the side thereof corresponding to the salient side of its bend, and means, arranged in the channel of said member and extending through the guides, for securing the guides to said member.
